UNITED STATES enoaonxnnnna, or CLEVELAND, onro.

srame LUBRIGATOR,

Application filed. February 17, 1926. Serial No. 88,862.

' V hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view showing partly 1n longitudinal section and partly in side elevation the preferred embodiment of my mven tion as applied to a vehicle spring.

Figure 2 is a top plan view of the same.

Figure 3 is an enlarged transverse section, taken in the plane indicated by the line 33 of Figure 1, looking toward the right.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The spring illustrated is made up 1n}conventional manner of a plurality of superposed leaves 1, the uppermost leaf being shown as terminating at its end in an eye' 2 in accordance with accepted practice.

My novel lubricator is illustrated as applied for use, and it will be noted that among other elements the lubricator comprises a receptacle 3, preferably, though not necessarily, of sheet metal. It will also be noted that the receptacle 3 is generally tapered in the direction of its length, and is closed at its comparatively large end by a transverse wall 1, and is also provided with a bottom wall 5 and side walls 6, the latter having inwardly directed longitudinal flanges 7 as shown in Figures 2 and3. At 8 the receptacle 3 is provided with a filling conduit that is normally closed by a cap 9, Figure 1.

Embracing the end portion of the receptacle 3 and also :embracing the spring are hangers 10 and 11, the said hangers being, of different sizes, so as to snugly receive and fit the large end and the small end, respectively of the receptacle3. Each hanger has inwardly directed upper arms and upstanding apertured cars 12 at the inner ends of said arms, and my invention contemplates the 1,635,327, PATENT 'QFFICEQ connection of said cars 12 through the medium of bolts 13 and nuts 14 or any other appropriate connecting devices.

Interposed between the flanges 7 and the uppermost leaf of the spring are gaskets or packing strips 15, preferably of corks, the function of which is to prevent leakage of oil or lubricant between the said flanges 7 and the uppermost leaf.

. Disposed in the receptacle 3 and under the end portions of the springleaves so as to be immersed in and saturated by oil and so as to feed oil to the end portions of the spring leaves-is a wick orstrip of absorbent material designated by 16. The outer end of the said'wick 16 is interposed between and held by the edge ofthe end wall 40f the receptacle 3 and one of the spring leaves, and it will be noted that the wick extends longitudinally through: the receptacle 3 and under the end portions of'the spring leaves" to the pointiwhere'the foremost or inner} most portion of the wick isclamped and held between, the upturned'flange 17 on the bottom wall of the receptacle 3 and the opposed surface of one of the spring leaves. It will also be noticed that adjacent to its innermost end the wick 16 is provided with side portions 18, Figures 1 and 3, the said side portions being interposed between the edges of the spring leaves and the side walls of the receptacle 3 so as to serve the twofold function of supplying oil to the leaves and preventing leakage of oil from the inner end of the receptacle 3.

It will be noticed that when properly supplied with oil at intervals, my novel device may be depended upon to adequately lubricate the leaves of a vehicle spring; and it will also be noticed that while there is no liability of my novel device being casually displaced in practice, yet when necessity demands the device may be expeditiously and easily removed from a springand this without the assistance of skilled labor or the employment of any tool other than an ordinary nut wrench.

It will further be noted that my novel device is simple and inexpensive'in construction, and in general is well adapted to with- I have entered-into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear'and exactunderstanding of the said embodiment. Idonot desire, however, to be understood as limiting myself to the precise const-ruction andar rangement of parts as disclosed, my invention being defined by my 'appendedclaims within the vscope "of which modifications in structure and'in arrangement may be made without departure from my invention.

'Having described-my invention, what I claim and desireto secure by Letters Paten-t, is: 1 i V v '1' 1-. A' spring lubrrcator; comprising areceptacle having a bottom, side walls rising from the bottomialong its longitudinal edges,

the upperedges of't'he sidewalls inclining longitudinallyand provided with inwardly directed flanges, an end wall rising from one 'endedge ofithe bottom and along the taller encliedgesof the side Walls and of a height sli-ghtlyless than the taller ends of the side Walls and havingiits upper extremities pro- 7 vided withan outwardly and upwardly directed flange, an, end wall rising from the other end edge of the bottom along the shorter end edges of the side walls and being less in height than said shorter ends of the sidewallsa'nd having its upper extremity provided iWlth an outwardly and downwardlydirected flange,-av capillary element havingits ends disposed over the outwardly directed flanges and its side edges disposed under the inwardly directed flanges, and

meansvfor suspending the receptacle below a leaf spring to supply the capillary element to the under-surface thereof so that lubricant. in the receptacle will splash against the capillary element to maintain the same saturated with the'lubricant.
